This invention relatesto certainnew and portionfand 'centrally thereof whereby cenuseful improvements linnagricultural ma.-` chinery and implements thereforfand especially to that' formV of implement employed for the cutting or closefcropping ofk weeds.y

Anv objectfofk the invention-consists of wheel regulating `and control v`members whereby the sides or the entire implement may be raisedV and lowered at will pursuant to the lconfiguration of the field. j. 1

Another object of the invention comprises operating members for controlling they angle and depth'cut of the implements. f

' Anadditional objectV ofthe invention contemplates the provision andarrangement of an operating lever having' operative engagement with the implement carrying structure y to tiltl same in different.V directionsin` the '3-3 of Figure 2.

Having described theinvention,-what is claimed fis f v -1. An agricultural implement comprising a chassishaving,` 'downwardly andfobliquely inclined -rearmost ends; implement carrying members eccentrically mounted foruniversal n movementupon'the*downwardly and obliquely inclined rearmostendsnfthe; chassis; an J operating 4leven carried? up on the chassis yhaving connection with the implement supportr ing Amembers .torock-theJ I"latter,` :and r lever .members having connection with. the vinnerf most; f ends:Y ofthe implement Vcarryimg; {mem- *bers to; angular-ly dispose the implement carrying members .-from fthe universal-connections therefor., Y t

2. an agrilcuitufai imple-ment 4 eqmprispag llt? a chassis having downwardly and obliquely inclined -rearmost ends, implement carrying members disposed in spaced rectilinear-alignment and eccentrically mounted for universal movement up on the downwardly and obliguely inclined rearmost ends of the chassis, ever members having separate linkage connections with the innermost ends of the `implement c carrying members to angularly 'dispose the implement carrying members from the universal connections therefor, and an operating lever mounted upon the chassis cooperatively associated with both linkage connections to s simultaneously rock the implement carrying ,n

members in a single operation.

3; An agricultural -implement .comprising "a chassis having implement carrying members disposed inspaced alignment and eccentrically mounted for universal movement thereon, lever members mounted upon the chassis having linkage connections with the innermost spaced ends lof the implement carrying members, an operating lever, and cony nectlng means for the operating lever having biting engagement with the linkage connections for simultaneously rocking the implement carrying members. 4. An agricultural implement comprisin a chassis having implement carrying mem-` bers disposed in spaced alignment and 'eccentrically mounted for universal movement:y

thereon, lever members having linkage connections with the innermost spaced endsof the implement carrying membersto angularly dispose the latter with relation to the chassis, a rock shaft mounted `upon the chassis, Aa

yoke member swingably supported upon the rock shaft andr slidably accommodating` the linkage connections, and an operating lever carried upon the chassis having operative connection with the rock shaft grippingly engaging the yoke member and linkage connections to impart simultaneous rocking Inotion to the implement carrying members.

In testimony whereof I affix my signature.
